Most renal artery aneurysms are asymptomatic and are often identified accidentally by computed tomography (CT) or ultrasonographic examination of other diseases. A 57-year-old female patient was diagnosed as having multiple saccular renal artery aneurysms with three outflow arteries at the right renal hilum on CT accidentally. One of the aneurysms was 26 mm in diameter, which was indicated for surgery due to a risk of rupture. Through median laparotomy, inferior vena cava was mobilized and good surgical field was obtained. After the administration of a renal protective solution, the aneurysms were resected and three outflow arteries were reconstructed by using a tailoring technique. Postoperative renal dysfunction could be prevented by an appropriate use of a renal protective solution and the reconstruction of all outflow arteries. One year and four months after the surgery, all outflow arteries were patent without stenosis and the reconstructed arteries did not re-expand.
